An Oregon mom whose body was found in a remote area after she was missing for nearly two weeks committed suicide, authorities said tonight.

Jennifer Huston killed herself by asphyxiation, the state medical examiner's office and police said Wednesday, according to the Associated Press. Huston's SUV was found Tuesday in a rural and remote area of Yamhill County, the Newberg-Dundee Police Department said.

Detectives and the medical examiner think the married mother of two young boys died "fairly close" to the time she was reported missing on July 25, police Capt. Jeff Kosmicki said in a statement. Detectives also found a note addressed to the woman's family, the AP reported.

Huston, 38, disappeared on July 24 after leaving to run errands. She was last seen at a gas station near Portland, Oregon. She also purchased trail mix, Gatorade and sleeping pills before she died, KATU reported.

Her family had been searching for her ever since, and her distraught husband pleaded for her return in an interview with ABC News last week.

He said he couldn't imagine his wife leaving her family of her own will. The couple had two sons, ages 2 and 6.

"She wouldn't leave all of us. She just wouldn't do this," Kallen Huston said. "Everybody who knows her agrees."
